COTTON-CHOPPER ATTACHMENT FOR CULTIVATORS.

Application filed April 6, 1922. Serial No. 550,076.

T 0 all whom it may concern:

Be it known that I, SILAS O. BRowN, a citizen of the United States,residing at Sulphur Springs, in the county of Hopkins and State ofTexas, have invented new and useful Improvements in Cotton-ChopperAttachments for Cultivators, of which the fol lowing is a specification.

The object of my said invention is the provision of a simple, durable,eflicient and easily manipulated cotton chopping attachment, designed tooperate and be handled between the gangs and under the seat of acultivator.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure1 is a vertical cross section of a cultivator equipped with my novelattachment.

Figure 2 is a detail perspective of my novel attachment.

Figure 3 is an enlarged detail section hereinafter explicitly referredto.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

The cultivator in general is of the ordinary well known construction andincludes a main frame 1, a drivers seat 2, gangs 3, an arched axle 4 andground wheels 5, mounted on the spindles of the said axle 4.

In furtherance of my invention an interiorly toothed gear 6 is attachedto one of the ground wheels 5, and a transverse shaft 7 is j-ournaled inappropriate bearings 8, attached to the upright portions of the archedaxle 4. Figure 1. At one end the said shaft 7 carries a spur gear 9 thatis intermeshed with the internal gear 6 as illustrated.

Appropriately fixed on the shaft 7 at about the center thereof, is abeveled gear 10, and pendent fro-n1 and adapted to swing forwardly andrearwardly on the said shaft 7 is a sleeve 11. J ournaled in the saidsleeve 11 is an upright shaft 12 having at its up per and lower endsbeveled gears 13 and 14:, respectively, the beveled gear 13 beingintermeshed with and adapted to derive motion from the beveled gear 10.

Carried by the sleeve 11 is a rearwardly extending and downwardlyextending beam 15 on which are handles 16. Interposed between the saidbeam 15 and loop-shaped arm 17 on the bearing sleeves 8 is a retractilevspring 18.

Journaled in the forward and rear portions 19 and 20 of the beam 15 is alongitudinal shaft 21 on which are carried chopping blades 22. At itsforward end the said shaft 21 is equipped with a beveled gear 23 that isintermeshed with the before mentioned beveled gear 14 on the shaft 12. y

In virtue of the construction described it will be manifest that thebeam 15 is capable of being readily swung from side to side and is alsocapable of being conveniently swung upwardly and downwardlyvwith theresult that the attendant who grasps the handles 16 is enabled tomanipulate the chopper to the best advantage.

It will be readily apparent from the fore going that my novel attachmentis susceptible of being readily installed in cultivators preferredembodiment of my invention in order to impart a full, clear and exactunderstanding of the said embodiment. I do not desire, however, to beunderstood as confining myself to the said specific construction andrelative arrangement of parts inasmuch as in the future practice of theinvention various changes and modifications may be made such as'fallwithin the scope of my invention as defined in my appended claim.

Having described my invention, what I claim and desire to secure byLetters Patent, is

In a cotton chopper, the combination of an arched axle, ground wheelsthereon, a gear carried by one of said ground wheels, a transverse shaftjournaled in bearings on the upright portions of the arched axle and,

bearing a gear intermeshed with the firstnamed gear, a pendent swingingsleeve connected with said transverse shaft, a miter gear fixed to saidshaft, an upright shaft journaled in the sleeve and having a miter gearintermeshed with the first-named miter gitudinal shaft journaled in thebeam and equipped with chopping means and having a beveled gearintermeshed with the beveled or miter gear at the lower end of theupright 10 shaft.

In testimony whereof I afiix my signature.

YSI'LAS 0. BROWN.
